Are people forgetting how to DRIVE?

Lately I've had cases where at two-way stops the person going straight just sits there and waits for me to make my left turn. Hello. The person going straight has the right of way. At four-way stops I've had people who have the right of way flag me to go so they can finish their text message. Is this happening to you?

Yes. I attribute it to the decline in school funding, which has made Driver Education in US high schools virtually nonexistent.

Decades ago we had to take classroom instruction, and have tests, that covered these very issues you mention. And then go out into traffic with dual-control cars, our driving instructor next to us.

You can't really learn this stuff studying a State driver's manual on your own, cramming to pass a written driver's test one time. And then passing a driving demonstration that is entirely contrived, nothing real-world about it. So that we've got several generations of drivers out on US roads who really don't know what the fuck they're doing.
